Abstract: Disclosed herein is a method of controlling operation of at least one light-emitting system including at least one light-emitting element. The method includes: a) monitoring at least temporarily, at least one electrical parameter of the light-emitting element; b) evaluating the electrical parameter and verifying if the electrical parameter meets at least one predetermined criterion; and c) taking at least one safeguard action depending on the outcome of step b).

Abstract: Disclosed herein is a spectroscopic light source. The spectroscopic light source includes: at least one light emitting element; at least one electronic circuit configured for applying electric power to the light emitting element; and at least one housing, where the housing at least partially surrounds the light emitting element; and at least two output channels going through the housing, where each one of the output channels is configured for decoupling at least one light beam from the spectroscopic light source. The spectroscopic light source is configured for independently controlling each one of the output channels.

Abstract: A device is disclosed. The device includes a. at least one radiation emitting element configured for emitting a modulated thermal radiation as a result of its temperature; where the radiation emitting element includes at least one incandescent lamp; and b. at least one electronic circuit configured for applying a periodic time-dependent voltage to the radiation emitting element, wherein where the electronic circuit is configured for controlling one or more of an amplitude, a duty cycle and a frequency of the periodic time-dependent voltage, where a temperature of the radiation emitting element and a frequency of the modulated thermal radiation depend on the applied periodic time-dependent voltage controlled by the electronic circuit.
